Huge sinkhole in East Java, Indonesia

An enormous sinkhole has opened in Surabaya, East Java, Indonesia.

A mine collapse in County Monaghan, Ireland, caused a large sinkhole to emerge on a football pitch.

6 cars were buried under the ground after a massive sinkhole opened up in the parking lot of the Tanger Outlets in Lancaster, Pennsylvania.

Sinkholes aren't rare in the area, but this one is especially large, geologists say

Geotechnical studies showed that connecting the sinkhole to Lake Saxon or rebuilding the roadway with sheet piles driven underground are too risky.

Large sinkhole opens up in Florida

The sinkhole begun to form on Friday, July 14, 2017, in the Pasco County's Land O' Lakes community near Tampa, western Florida and has already swallowed two houses.

A large expanding crack appeared in Northern Cape, South Africa, between the cities of Daniëlskuil and Kuruman, following the heavy rains that hit the region at the beginning of January. 

On Tuesday, November 8th, two small sinkholes formed beneath a 5 lane street in Fukuoka, Japan.

Late last week, the Mosaic Company released a statement informing the people of Polk County, Florida that a sinkhole had formed on the grounds of a fertilizer plant they operate. They went on to say that over 215 million gallons of "slightly radioactive" water flowed into the sinkhole and subsequently into the local aquifer.

Earlier this month on August 2nd, a large sinkhole formed in the backyard of a country home in Ipswich, Australia. The home owners, retired couple Ray and Lynn McKay, have moved out while it is determined if the sinkhole will grow and endanger their home. The sinkhole has grown to 8 meters in diameter.

A neighbor alerted the McKay's of the sinkhole in the morning on August 2nd. At the time, the sinkhole measured only 1 meter across, but has since grown dramatically. Due to the amount of water it contains, local utility companies originally believed a water or sewer pipe had burst, but it was determined that there were no pipes in the area.

Authorities now believe that the sinkhole may have been caused by a collapse or flooding of abandoned mine shafts that are found throughout the area. The Department of Environment and Heritage Protection are working to repair the damage and return the McKays to their home.
